TUBULAR LEVEL INDIACTOR

As the liquid level rises in the tank, the float is lifted up due to buoyancy. The float moves inside a SS float chamber. External to this float chamber is a glass tube(MLI 2200)/indicating PVC magnetic ball assembly (RBMLI 2200) which carries the magnetic follower. Due to magnetic attraction, the magnet on the float and the magnetic follower are coupled and move in union. So as the float moves along with the liquid, the follower capsule also moves inside the glass tube(MLI 2200) and PVC magnetic ball changes its colour (RBMLI 2200), and the position of the follower capsule/magnetic ball can be read against the scale.
